Add an Admin Overview as the Admin landing (default when you open Admin): an
ops/health board distinct from the user Dashboard. Four cards built from data
we already generate — Updates (update_status.json, with one-click update),
Backups (backup dashboard.json), SSH & Security (access.json), System
(disk/memory/system_info) — each with a Manage link into the right section.
Styled like the backup dashboard (tiles/status dots).
Wire-up: 'Overview' is the top sidebar item and the default category
(handleConfig + sidebar), rendered by AdminOverview into #config-section via a
renderConfig('overview') special case. Every Admin page now shows the same
'Admin' breadcrumb header (Overview, SSH Access, and the config categories) for
a consistent Admin → Section feel. User Dashboard gets an 'Admin overview →'
link.
